We assert that having at least one 40 Cosmic Explorer detector is integral in achieving the key science goal of Cosmic Explorer as it outperforms a 20 in all science goals other than the access to post-merger physics.
Research into mitigating SEC losses is key to the success of the 20 Cosmic Explorer detector to achieve the science goals that depend on achieving improved high-frequency sensitivity.
[1]} and the [2]} assert that a network of third-generation detectors is indispensable.
In particular, the precise determination of the source redshift and sky localization necessitates a network of three third-generation detectors—two Cosmic Explorer and Einstein Telescope. The key findings and benefits from tuning are summarized in the tab:sumry.
Lastly, we note that we consider a handful of metrics to quantify the performance of different tuned configurations. We urge the broader gravitational wave astronomical community to perform in-depth analysis other than the SNR metric used in the study.
